Color Television Receivers

The NTSC Color Television Standards

When a conventional black-and-white receiver is tuned to transmissions conforming to the NTSC color standards the receiver responds fully to the first signal (the “brightness signal”) and recreates from it an image in black-and-white having a quality equal (or superior) to that provided by present black-and-white standards. Because of the nature of the chromatic signal, no normally perceptible ...

Measurements and Analysis of Secondary User Device Effects on Digital Television Receivers

This article presents results from a study of the potential effects of secondary users operating in unoccupied television spectrum. Television spectrum is known within the wireless communications community as being underutilized, making it a prime candidate for dynamic spectrum access. The proposed use of this open spectrum has prompted questions concerning the quantity of available channel spa...

Dosimetry of the Very Weak X-radiation Generated in Television Receivers and X-ray Diffraction Apparatus

With many kinds of apparatus in which electron tubes are operated at high voltages, the possiblepresence of very weak, soft Xvradiation, (i.e. Xradiation of low penetrating power) in the neighbourhood must be given due consideration. The question arises in such apparatus as X-ray diffraction equipment, formerly found only in research laboratories but now widely used industrially in inspection a...
